摘要
用超声辅助法提取红花黄色素,通过单因素和正交试验对提取工艺进行了选择,研究了红花黄色素在紫外照射、酸碱度、不同金属离子下的稳定性。结果表明:当超声功率80 W,超声时间40 min,超声温度45℃时红花黄色素提取效果最佳,同时红花黄色素具有较好的耐酸性以及抗紫外性。
Safflower yellow was extracted by ultrasound -assisted method and extraction concl^tlons were optimized by single factor and orthogonal experiment. Stability of safflower yellow under UV ir- radiation, pH, metal ions and temperature was investigated. The results showed that the optimum con- ditions for extraction of safflower yellow pigment：ultrasonic power 80 W, ultrasonic time 40 min, ul- trasonic temperature 45 ℃. Safflower yellow pigment has good thermal stability, acid resistance and UV resistance.
